Noble Kaguya
From Japanese old fairy tale "Bamboo-cutter Story"

She tells the old foster-parents
who found her in a bamboo thicket
and have brought her up with lots of love:

"I am not a common human being in this world.
I am a Moonian.
I came down from the Moon as I was destined to.
And now it's time for me to return home.
My compatriots are coming for me on the night of next Full Moon.
I must go with them.
I've been in sorrow since last spring to think that you will grieve over my leaving."
